At least one more original Ghostbuster wants to come back for the long-discussed third “Ghostbusters” movie. Ernie Hudson, who plays Winston Zeddemore in the 1984 classic and its 1989 sequel, says a third movie is a good idea — and he wants in.

“I would love to see it happen,” he tells The Post. The original 1984 movie celebrates its 30th anniversary with a special one-week release in theaters beginning Friday.

Hudson, however, has one caveat: They need to pay him better than he was paid for the first two.

“I think my character says in the movie, ‘If there’s a steady paycheck in it,’ ” notes the 68-year-old.

Dan Aykroyd, who played Ray Stantz, has also said he’d appear in the film. Hudson hasn’t yet been approached for a role, and the film is far from a reality: It’s been in talks for years as it’s bounced around development hell.

The project hit another roadblock in March when Ivan Reitman — who directed the first two films — pulled out following the death of Harold Ramis, who played Egon Spengler. Reitman been working on a script with “The Office” writers Lee Eisenberg and Gene Stupnisky — rumored to be a reboot to the series — in which the original characters pass the torch to a new cast of ’busters. Recent rumors say the squad may be all-female in the new film, too.

In early August, producers started courting “Bridesmaids” director Paul Feig, according to the Hollywood Reporter. Filming could begin in 2015 if everything comes together.

But still, Hudson — who starred in HBO’s “Oz” — says he’s optimistic.

“It could happen for a lot of reasons,” he says. “The fans have been really pretty extraordinary.”

But because Ramis died, the sequel would have to differ from the originals.

“I don’t think you can do a quote-unquote ‘Ghostbusters’ movie and try to create that same magic without Harold Ramis,” he says. “But they could do something. The fans want it to be a really creative and fun movie.”

Would everyone’s favorite Ghostbuster/party crasher Bill Murray be involved? The quixotic comedian has hinted that he’d entertain the idea of returning as the charmingly snarky Peter Venkman, but didn’t seem too enthusiastic about it.

Hudson, for one, wants him on board.

“I love Bill Murray. I would love to work with Bill Murray on ‘Ghostbusters’ or anything else,” he says. “Bill is probably the only guy I would attach the term ‘genius’ [to].”
